When booting BeagleV with 5.13.rc2 or 5.13.rc3 kernel, onece out of 10, it fails to detect builtin usb hub and hangs. These are the logs.

Just one annec-datapoint: I just hit this for the first time, but I had just updated the U-Boot. With the older U-Boot (and the same esmil-kernel-20210521-a22fc12 kernel) I hadn't hit it.

I forgot how to reproduce it. I used the u-boot from https://github.com/starfive-tech/u-boot/tree/Fedora and the kernel from https://github.com/esmil/linux/
